EDWARD E. BRADLEY, 0F STONINGTON, CONNECTICUT, ASSIGNOR TO THE ATWOODMACHINE COMPANY, OF STONINGTON, CONNECTICUT, A CORPORATION OF NEWJERSEY.

WARPING-MACHIN E.

To all whom it may concern:

Be it known that I. Flnwann E. BRADLEY, a citizen of the United States.and resident of Stonington .'in the county of New London and State of(,onnecticut, have invented a new and useful Improvement in \Varping-Machines, of which the following is a specification.

My invention relates to a warping machine and more particularly tomechanism for registering the length of yarn wound on the reel, and forpreventing the machine from reeling more than the predetermined lengthof yarn.

The present application is a division of my pending application SerialNo. 772,141.. filed June 6, 1913; the latter being directed moreparticularly to mechanism for shifting the warp threads along the reedsto prevent the cutting or wearing away of the reed.

A practical emlmdiment of the invention is represented in theaccompanying drawings in which,

Figure 1 is a view in side elevation. the peripheral portion of thereel, the warp separating reed and parts associated therewith beingomit-ted.

Fig. 2 is an enlarged detail plan view of the driving mechanism. r

Fig. 3 is an enlarged view in detail showing the registering device andparts associated therewith, the registering device being shown in faceelevation.

Fig. 4: is asimilar view taken at an angle of 90 to the view in Fig. 5,and

Fig. 5 is a top plan view of the same. the frame being broken away toshow the locking dog. The latter is shown in full lines out of itslocking position and in dotted' lines in locking position.

The frame of the machine is denoted by l, and may be of any well knownor approved construction for supporting the sen eral operative parts.The reel for winding the yarn is denoted by 2, and is mounted insuitable bearin in the present instance, on roller bearings 3, supportedupon suitable brackets 4. on the main frame.

The reel shaft is denoted by 5, and is provided with sprocket wheels.not shown in the present application. but shown in the applicationSerial No. 772.141. of which this is a division, and sprocket chainsleading Specification of Letters Patent.

Divided and this application filed January 23.

thence to opposite ends of the wheel. all as shown in said parentapplication. for enabling the operator to manually operate the parts toset them in proper position for starting under power. Referring toFig. 1. a drive belt 13 is shown leading to a pulley llon the machinefrom a suitable source of power. not shown. and from the shaft'l5 of thepulley ll, power is transmitted through a belt 16 to a pulley 17 on ashaft 18. for driving the reel, the latter in turn being arranged todrive the registering mechanism.

The reed frame. the means for giving it the usual transverse motion. thehand wheel for returning the frame to its point of starting and the.guide bar in cooperative relation to the reed frame and over which thewarps, pass after passing through the reeds, together with the means forshifting the guide bar, are matters particularly shown, described andclaimed in the parent application above referred to and are notparticularly shown and described herein.

For registering the length of 'yarn to be reeled, the shaft 5 of thereel is provided with a worm 80, see Figs. 3 and l. which engages theteeth of a worm wheel 81, the side of which is divided into sectionsindicating in the present instance, yards. The immerals in theillustration given are placed at one-sixth of a circumference apart. theinterval between the two numbers being the distance which theregistering wheel 81 will move for winding one hundred and twenty yards011 the reel; For each 'ofthese subdivisions of' one hundred and twentyyards, a

pin 82' is set in the side of the wheel 81, which pin in passing apredetermined point, engages the toe S3 of a pivoted hammer St and ringsa. bell S5 to warn the operator at the conclusion ofthe winding of eachone hundred and twenty yards. In order to determine the number of yardswhich it is desired to wind on the reel at one time, a finger 86 ismounted co-axially with the wheel 81, so tlfat it maybe swung intoposition to engage an actuating mechanism at any desired point withinthe limits of the registering wheel, that is, in the present instance.

up to seven hundred and twenty yards. The

shank of the finger S6 provided with a laterally elongated slot ST.through which the finger 86 may be fixed to any one of the g misses sixarms 88 of the wheel 81, by means of the set screw 89, and furthermore,the finger 86 may be set at any point intermediate of two arms byswinging it in the one direction or the other along the slot 87 beforeclamping it by the screw 89. \Vhen the finger 86 has been set in thedesired position, it will, upon the completion of the winding of thedesired number of yards, engage the end 90 of a rocking latch 91, seeFig. l. and lift it out of engagement with the pin 92 on a shaft 93 andthereby permit the shaft under the ten sion of a spring 9- to rotatesuificientlv to swing a stop arm 95, over the end of a projection 96 onthe end of the lever which carries the drive shaft 18, thereby lockingthe lever 63, controlled by the pedal (31, against being lifted by thedepression of said pedal and thereby preventing the engagement of thefriction drive pulley 59 with the rim (it) on the reel.

As the reel is rotated to wind the yarn only so long as the operator hasthe lever (33 depressed by means of the pedal (51, and as the operatorwarned by the bell, which strikes at the limit of each section of onehundred and twenty yards wound, watches for the finger S6 to drop thelatch 91 and removes his foot from the pedal as the latch is dropped,the movement of the pulley 55) away from the reel to stop its action,will spring back the stop arm 95 sufficiently to permit the extension 96to pass it and the stop arm will then promptly swing into position overthe extension 96, so that no further winding action will take placeinadvertently or otherwise until the stop arm 95 has been manually swungback into position out of the way of the extension 96 and the latch 91turned down in position to engage the pin 92, thereby holding the stoparm 95 out of position.

In practice, the operator quickly lifts his foot from the pedal andplaces a mark as the bell rings at the end of each interval of onehundred and twenty yards, throughout the winding of the section, and thestop finger is so placed that it will lock the friction drive pulleyagainst motion toward the driving rim on the reel when the end of thesection has been reached, so that the reel cannot be started again inthe event the operator should inadvertently try to do so either fromforgetfulness or otherwise.

Whatl claim is:

In a warping machine, a reel, a registering wheel driven by the reel, afinger carried by the registering wheel, a lever, a reel driving pulleymounted on the lever and movable with the lever toward and away from thereel, a spring actuated stop in position to lock the said lever andhence the driving pulley against movement toward the reel and a swinginglatch under the control of the finger on the registering wheel for releasing the said spring actuated stop.

In testimony, that .l claim the foregoing as my invention, 1 have signedmy name in presence of two witnesses, this fourteenth day of January1914.
